Specification 529,454 is referred to.ALSO:The invention comprises (1) aminoazo compounds of the formula <FORM:0690173/IV (c)/1> where n is 0-4, X is COOH or CONH2 and Y is hydrogen, methyl, ethyl, propyl, methoxy, ethoxy or propyloxy; (2) disazo dyes obtained by coupling diazotized (1) with p-coupling N-disubstituted anilines where the substituents are methyl, ethyl, propyl, hydroxyethyl, hydroxypropyl or dihydroxypropyl; (3) textile materials of an organic derivative of cellulose coloured with (2).  The monoazo compounds are made by coupling diazotized p-nitraniline with an amine of the formula <FORM:0690173/IV (c)/2> examples being given of the use of 3-amino-4-methoxy-oxanilic acid, 3-amino-4-methoxy-succinanilic acid and 3-amino-4-methoxy-succinanilamide.  Other suitable middle components are listed.  The end component preferably contains the group R.CO.NH- mto the disubstituted amino group, R being hydrogen, methyl, ethyl or propyl; a list of suitable components, with and without the m-acylamino group, is given.  For colouring textile materials, the monoazo compound is first applied to the fabric, e.g. as a dispersion from an aqueous bath or by mechanical impregnation from an alcoholic bath followed by steaming.  After rinsing, the aminoazo compound is diazotized on the fibre and the latter immersed in a solution of the end component.  Discharge effects are obtained by printing or stencilling with a paste containing a metal formaldehyde sulphoxylate, a thickener and swelling agent.  Coloured discharges are produced by the inclusion of a dyestuff in the paste, especially a vat dyestuff.  In the examples: (1) cellulose acetate is dyed with 41 - nitro - 3 - methoxy - 4 - aminoazobenzene-6-oxanilic acid from an aqueous bath containing Turkey Red oil, soap and salt; the dyed fabric is then diazotized with sodium nitrite and sulphuric acid and coupled with 3 - diethanolamino - acetanilide.  A white discharge is produced by applying a paste of sodium formaldehyde sulphoxylate, sodium thiocyanate and textile gum, steaming and soaping; (2) cellulose acetate is dyed with 41 - nitro - 3 - methoxy - 4 - aminoazobenzene - 6 - succinanilic acid from an aqueous alcoholic bath containing sodium thiocyanate; further treatment follows as in (1); (3) as in (1) using 41-nitro - 3 - methoxy - 4 - aminoazobenzene - 6 - succinanilamide.  The p  process is also applicable to the colouring of other cellulose esters, cellulose ethers, nylon and fibrous copolymers of vinyl chloride with vinyl acetate or acrylonitrile.
